Recently, we developed a method using FT-IR spectroscopy coupled with partial least squares (PLS) regression to measure the four most abundant organic functional groups, aliphatic C-H, alcohol OH, carboxylic acid OH and carbonyl C = O, in atmospheric parti ...
Organic tracer-based positive matrix factorization (PMF) was used to apportion fine particulate (PM2.5) organic carbon (OC) to its sources in Centreville, AL, USA, a rural forested site influenced by anthropogenic emissions, during the Southern Oxidant and ...
During the 2013 Southern Oxidant and Aerosol Study, Fourier transform infrared spectroscopy (FTIR) and aerosol mass spectrometer (AMS) measurements of submicron mass were collected at Look Rock (LRK), Tennessee, and Centreville (CTR), Alabama. Carbon monox ...
The deactivation pathways of sulfonated carbon catalysts prepared from different carbons were studied during the aqueous‐phase hydrolysis of cellobiose under continuous‐flow conditions. The sulfonation of carbon materials with a low degree of graphitizatio ...
Lately, black carbon (BC) has received significant attention due to its climate-warming properties and adverse health effects. Nevertheless, long-term observations in urban areas are scarce, most likely because BC monitoring is not required by environmenta ...
Biogenic secondary organic aerosol (BSOA) contributes significantly to summertime organic particulate matter. In this study, a simulation of BSOA for summer 2012 over China is performed using the Community Multiscale Air Quality model with an explicit repr ...
In this work, we studied catalytic formic acid dehydrogenation with a homogeneous RAPTA type precatalyst in aqueous solution. The effects of an amino group, attached to the arene, and the impact of a second equivalent of 1,3,5‐triaza‐7‐phosphaadamantane (P ...
Natural gas is receiving increasing awareness as fuel for passenger vehicles due to its very low specific CO2 emissions. However, control of CH4 emissions from natural gas combustion in stoichiometric engines requires a specific three-way catalyst (TWC). T ...
In homogeneous catalysis, the structure and electronic config-uration of the active catalysts can vary significantly. Changes inligation, oxidation, and spin states have the potential to influ-ence the catalytic cycle energet ics strongly that, to a larged ...
Large reductions of sulfur and nitrogen oxide emissions in the United States have led to considerable improvements in air quality, though recent analyses in the Southeastern United States have shown little response of aerosol pH to these reductions. This s ...
